The term "class time" refers to the actual in-person instructional hours that students spend attending a course or lecture. It is typically used when referring to traditional, face-to-face education settings where students physically attend a classroom and receive direct instruction from a teacher or professor. The amount of class time can vary depending on factors such as the type of institution, course level, and instructor's teaching style. Class time may also include breaks, exam periods, and other scheduled activities related to the course.
